LockNLube® Grease Coupler XL

10 Sep 2023

imageThe LockNLube® Grease Coupler XL is a longer version of the best-selling original. It features the same unique sliding sleeve that’s operated by a thumb lever. 4 hardened-steel jaws lock onto the grease zerk, creating a leak-proof seal and preventing the coupler from coming loose. With almost four inches or reach, it is especially suited for recessed Zerks such as those found on shielded PTO shafts, axles, U joints and harvester heads. It releases easily, even under extreme pressure. The LockNLube® fits all 1/8” NPT hoses and is compatible with all grease guns. It comes with a 30-day money back guarantee and sells for $39.95 including S&H in the U.S.
